However, whether it is a reflective or transmissive plasma light-emitting panel, the surface temperature of the light-emitting surface is usually as high as 40 ° C to 60 ° C, which tends to cause heat dissipation during long-term operation. It is easy to have a negative impact on the liquid crystal display panel and reduce the display quality and service life of the liquid crystal display panel. Therefore, how to effectively improve the heat dissipation efficiency of the plasma light-emitting panel has become an important issue that cannot be delayed. Summary of the invention
